How Are Seasonal, Avian and Pandemic Influenza Different?

Seasonal Influenza is a contagious respiratory illness caused by influenza viruses. Seasonal influenza outbreaks occur every year.

Avian Influenza is caused by avian influenza viruses, which occur naturally among birds.

Pandemic Influenza is flu that causes a global outbreak of serious illness that spreads easily from person to person. On June 11, 2009, the World Health Organization (WHO) raised the worldwide pandemic alert level to Phase 6 in response to the ongoing global spread of the novel influenza A (H1N1) virus. A Phase 6 designation indicates that a global pandemic is underway.
